Question

3x - 5y = 25
x = y + 7

Answer 1

ummm so do u need to use subsitution or elimination?

Answer 2

substitution

Answer 3

ok that is easy

Answer 4

3(y+7)-5y=25

Answer 5

Can u solve from there?

Answer 6

can you show me the next step? then I think I can from there... I understand a little better

Answer 7

so we open up the brackets and gather like terms
3y+21-5y=25
21-2y=25
-2y=3
y=(-3/2)
Now plug this into the second equation to find out what x equals

Answer 8

Then to check your work plug in the x and y into both equations and if the answer is correct then you know u got the correct answer

Answer 9

okay! Thank you so much. I think I got it now.
